Description of the Related Art In recent years, there has been an increasing interest of individuals in health management such as self-health checking for the purpose of early detection of a disease and health management during or after treatment of the disease. Therefore, the applicant of the present application has previously proposed in Japanese Patent Application Laid-Open No. 9-281102 a urine analyzer for sampling urine excreted by an individual in a toilet on the spot and analyzing predetermined components contained in the urine. The proposed urine analyzer includes a urine collection unit and a control analysis unit, and the urine collection unit has a urine collection container for receiving urine, a support rod supporting the urine collection container, and a support rod that is stored in the urine collection container. Piping and the like for sending urine to the urine component measuring device of the control analysis unit are provided. Further, a net-shaped part is attached to the urine collection container in order to prevent urine from bouncing off.

る。However, urine stones are gradually deposited in the urine collection container and in the piping for sending urine to the urine component measuring instrument, causing problems such as emission of an odor and clogging of the piping. . Tap water is usually used as cleaning water, and means such as using a dedicated detergent or mechanically cleaning a cleaning brush has not been put into practical use due to cost and maintenance. Urinary stones are produced by the growth of bacteria that use urine as a nutrient source that cannot be completely washed, convert urea into ammonia to make it alkaline, and thereby precipitate calcium dissolved in the urine. Once the urolith adheres, it cannot be removed with a neutral detergent. Since urolith is porous, it becomes a hotbed of bacteria and further promotes adhesion of urolith.

でも十分に尿石付着を防止することは難しい。There are two conceivable means for preventing the adhesion of urine stone. The first is to completely remove urine in the washing process. The second is to prevent bacterial growth. If the bacteria do not multiply, the mechanism of urolith adhesion will not work, and urolith will not adhere. The first means is to carefully wash with washing water. However, a large amount of washing water is required, and it is difficult to sufficiently prevent adhesion of urolith simply by washing with washing water. Ag, Cu as the second means
Such a method has been adopted in which a metal such as is kneaded into a resin that is a material of a urine collection container, and bacteria are sterilized by these metal ions that are slightly dissolved from the material surface. The above-mentioned resin into which Ag and Cu are kneaded, that is, a so-called antibacterial resin, is deteriorated in antibacterial performance when used in a place where water is constantly exposed to water, and it is difficult to sufficiently prevent adhesion of urine stone even by this means.

影ができないように取り付けるのが望ましい。The urine collecting unit 10 of the urine analyzer is made of a material transparent to ultraviolet light (wavelength 370 nm), for example, acrylic resin, norbornene resin, fluororesin, polyethylene resin and the like. A light-emitting diode 15 that emits ultraviolet light is mounted in a urine collection container 11 that receives urine from the urine collection unit 10. The light emitting diode 15
Is connected to a control device (not shown) by a light-emitting diode wiring 15-1 (partially omitted in the drawing) in the support rod 13. The surfaces of the urine collection container 11 and the urine collection unit 10 are coated with titanium oxide, which is a photocatalytic semiconductor material. The inner wall surface of the urine collection unit 10 that houses the urine collection container 11 is similarly coated with titanium oxide,
Further, a light emitting diode 16 that emits ultraviolet light for optically exciting titanium oxide is attached (see FIG. 4).
Similarly to the light emitting diode 15, the light emitting diode 16 is connected to the control device by a light emitting diode wiring (not shown). The urine collection container storage part to which the light emitting diode 16 is attached is not limited to the part shown in FIG. 4, but is an arbitrary part in the urine collection unit 10. Further, the number of the light emitting diodes 15 and 16 mounted in the urine collection container 11 and the urine collection unit 10 for emitting ultraviolet light does not need to be one, respectively. Is desirable.

む有機物が分解される。After the urine collection is completed, the urine collection container 11 is housed in the urine collection unit 10 as shown in FIG. 2 and is washed with washing water injected from a nozzle 17 provided in the urine collection unit 10. After this washing, ultraviolet light is emitted from the light emitting diode 15 in the urine collecting container 11 and the light emitting diode 16 in the urine collecting unit 10. The titanium oxide coated on the walls of the urine collection container 11 and the urine collection unit 10 is photo-excited by the ultraviolet rays emitted from the light emitting diodes 15 and 16, and organic matter including bacteria in contact with the titanium oxide surface is decomposed.

よい。Light emitting diodes have a long life and low power consumption. The light emitting diodes 15 and 16 are always lit when the urine collection container 11 is not used (when the urine collection container 11 is stored in the urine collection unit 10). On the other hand, ultraviolet light is harmful to the human body, especially to the eyes.
In the first use (when the urine collection container 11 is out of the urine collection unit 10), the light is turned off. Light emitting diodes 15 and 1
6 is arranged outside the urine collection container 11, inside the urine collection container 11, and in the urine collection unit 10 so as not to form a shadow of ultraviolet rays,
It goes without saying that the material constituting the urine analyzer 1 does not have to be a material that transmits ultraviolet light. The light emitting diodes 15 and 16 need not always be lit, but may be pulsed.
